What procedures are followed to rewrite expressions involving radicals and rational exponents

Step-by-step explanation:

The following procedures you can keep in the mind while writing expressions involving radicals and rational exponents.

1) If equation is like this

you can write it as

here the order doesn't matter whether you take the power of x and then take the root of it or first you take the    root of it and then find its power.

2) Fractional exponents are roots and nothing else for example

doesn't mean but it means .

3. The final answer should be in the same format as the original problem; if the original problem is in radical form, your answer should be in radical form. And if the original problem is in exponential form with rational exponents, your solution should be as well.

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
